Cat’s-Claw Vine, Dolichandra unguis-cati : A Showy but Invasive Plant in Florida


Cat’s-claw vine is a neotropical, climbing perennial that produces large and showy yellow flowers in the springtime. Unfortunately, the aggressive nature of the vine has made it a major weed in China, Australia, South Africa, and parts of the southeastern United States. This 6-page fact sheet written by Niels Proctor and Jason Smith and published by the UF/IFAS School of Forest Resources and Conservation provides guidance on identification and control of this invasive vine and suggests some similar native vines to use instead.

New and Revised Featured Creatures, September and October 2017

Founded in 1996, Featured Creatures provides in-depth profiles of insects, nematodes, arachnids and other organisms. Their website is a cooperative venture of the University of Florida’s Entomology and Nematology Department and the Florida Department of Agriculture and Consumer Services’ Division of Plant Industry. EDIS hosts copies of these profiles in fact sheet format. In September and October, the following have been added:

Carbon Stocks on Forest Stewardship Program and Adjacent Lands

Pine trees in a forest

Nonindustrial private forestlands in Florida provide many environmental benefits, or ecosystem services. Ecosystem services are benefits from nature that are directly enjoyed, consumed, or used by humans, such as water quality improvement or protection, recreation, biodiversity, and even timber. Another benefit from forests that is gaining interest is their ability to store carbon through the photosynthetic capture of carbon dioxide, a greenhouse gas, in tree, plant, and soil biomass. The carbon dioxide that is stored over the life of a forest, called carbon stocks, is not only important for mitigating greenhouse gas contributions to climate change, but it can also be valued in several markets and incorporated into environmental policy instruments. This 5-page fact sheet was written by Nilesh Timilsina, Francisco J. Escobedo, Alison E. Adams, and Damian C. Adams and published by the UF Department of School of Forest Resources and Conservation April 2017.

Pest Identification Guides, August 2016

Created to help growers and crop consultants, private homeowners, Master Gardeners, and the general public identify common arthropod pests and the damage they inflict, each field guide provides photos of the important life stages and crop damage associated with arthropod pests. The text highlights key general morphology and biology, distribution, and natural enemies. Written by Jeffrey Cluever and Hugh Smith, and published by the UF Department of Entomology and Nematology.

NOTICE: EDIS may be affected by computer outage this Saturday, August 13th

The EDIS website (http://edis.ifas.ufl.edu) may be down on Saturday starting at 8:00 a.m. due to maintenance on the power supply to the main server on UF's main campus. Although EDIS servers are among those impacted by the planned outage this Saturday, we are accelerating our migration schedule in the hopes that we can move off of the affected servers before the end of the week.

If the migration proves too complex to manage on short notice, the website will be down. Print ordering and publication approval (Workflow) sites, as well as the authoring tool, may be down as well.

Estimated Costs and Regional Economic Impacts of the Oriental Fruit Fly (Bactrocera dorsalis) Outbreak in Miami-Dade County, Florida

Adult female oriental fruit fly, Bactrocera dorsalis (Hendel), laying eggs by inserting her ovipositor in a papaya.

Oriental fruit flies, very destructive pests of fruits, were first detected in the Redland area of Miami-Dade County on August 26, 2015, and as of January 2016, 165 flies had been captured. This triggered an eradication program and establishment of a quarantine area composed of agricultural operations and nonagricultural properties, such as residential and commercial areas. As part of the effort to eradicate the fruit fly, growers and packers in the quarantine area are required to sign a compliance agreement that outlines the procedures necessary for harvesting, handling, and postharvest processing of agricultural products that may serve as hosts for any life cycle of the fruit fly. This 12-page fact sheet written by Sergio Alvarez, Edward A. Evans, and Alan W. Hodges and published by the UF Food and Resource Economics Department provides estimates of the direct and indirect losses to Florida’s agriculture and related sectors as a result of the outbreak and ensuing quarantine and eradication programs.

US cattle markets have experienced a roller coaster ride over the last several years, with cattle prices have been supported by a declining US beef cow herd and strong beef demand. But a turning point in the US cattle industry occurred at the beginning of 2015. This 7-page fact sheet witten by Chris Prevatt and published by the UF Department of Food and Resource Economics includes highlights of the US cattle market’s cycle since 2004 and the estimated outlook for 2016, a brief analysis of the supply situation, food and forage conditions, demand and trade, competing meats, and the 2016 beef price outlook.

A survey of Florida fresh citrus packers was conducted in April 2015 to collect data on their packing charges during the 2014/15 season. A total of sixteen packinghouses participated in the survey, seven from the Interior region and nine from the Indian River region. The average of their responses was computed to obtain the estimates presented in this 4-page fact sheet was written by Ariel Singerman, and published by the UF Department of Food and Resource Economics, March 2016.
